Application September 18, 1939, Serial No. 295,178

This invention relates to paper imitation reed and the method of forming the same. It has for its objects:

First, to produce a new and improved paper imitation reed of concaVo-convex form.

Second, to provide such a reed formed of 'a folded strip of paper in which the seam comes substantially at the edge of the reed so that it is concealed from View when the reed is woven and does not scuif up during the use of the fabric or the like made from the reed.

Third, to provide such a reed which is so formed that it will retain its shape without the use of adhesive.

Fourth, to provide anew and improved method of making concavo-convex reeds.

Fifth, to provide a method by means of which a single strip of paper may be folded to form I the concavo-convex reed with the seam substantially at the edge of the reed.

Sixth, to .provide such a method in which the use of adhesive is eliminated. Other objects and advantages pertaining to details and economies of construction and opere ation will appear from the description to follow. The invention is defined in the claims. A preferred embodiment of our inventionis illustrate in the accompanying drawings, ln which:

Our new and improved reed I is made from a single strip of paper 2. Ihe edges 3 and 4 are 56 folded to a line indicated at 5 which extends lonof a portion of a strip of reed made in'accordanceA gitudinally of the strip and is spaced from the center line of the strip. After this fold has been made, the paper is moistened and isthen folded along the line I as shown in Fig. 4. It will be noted that'the wider .portion I ofthe strip formed 5 by the fold on the line 5 has its upper edge 1 extending slightly beyond the free edge 8 of the narrower portion l formed by the fold along the -1 line 5. l 1

After the fold along the line 5, the paper strip 10 is given a concave-convex form .shown in Fig. 5. The wider portion 8 formed by making the fold along the .llnei overlies the convex side IIl of the narrower portion 9 and the free edge 1 of the wider portion. 9 is forced slightly around the free l5 edge 8 of the narrower portion 9 to lock the pieces in position.

In Fig. 6. we show the folder II which makes the first f old in the strip 2. It is a conventional folder having wings I2. After the strip has been 20 folded by the folder I I. it passes to a folder I3 which folds the strip `along the line 5. The strip 'is continually advancing and is pulled through a die H forming part of the folder I3. The creasing is accomplished by the blade I5.

.T After the fold is made on the line 5, the strip passes to a wheel I6 to the surface of which water is applied. The water moistens the folder in edges 3 and 4 of the strip through contact as is best shown in Fig. 9. Thereafter the strips are 30 folded together 'by the die I1 and then ,passed to forming Vwheels I8 and I9 which give the concavo-convex form. It will be noted that the wider portion G formed by the folding on the line 5 extends beyond the 35 free edge l of the narrower portion 9 vformed by the fold I. The nal reed is somewhat narrower than the wide portion 6 formed by folding on the line I and it is the nal pressing operation which gives this form that forces the free edge I of the 40 portion 6 slightly-around the free edge 8 ofthe narrower portion 9. The paper, being moist, re- I tain's its form and the overlap of the f ree edge I tends to hold the reed in Aits iln'al form; The

seam 2l lies substantially at the edge of the 45 finished It will be apparent that the reed made in accordance with our invention is highly satisfactory because the seam 2II is not exposed when the reed is made up into fabric. 50

We have found that by following the method above-described. lt i's possible to. greatly increase the speed of manufacture. Whereas in the past it has been possible vto produce onlyabout 300 feet per minute of paper imitation reed where adat the rate of 500 feet or more per minute.

The particular form given to the reed makes it possible to eliminate the use of adhesive and the application of water as we apply it tends to give the form permanence.

The terms and expressions which have beenherein employed are used as terms of description and not of limitation, and there is no intention, in the use of such terms and expressions, of excluding any equivalents of the features-.shown and described, or portions thereof, but it is recognized that various modifications are possible within the scope of the invention claimed..

Having thus described our invention, what we claim as new and desire to secure by Letters 'Patent is:

1. A concavo-convex paper imitation reed comprising a paper strip having its edges folded to a longitudinal line one side of the 'center line of said strip and folded at said line with the folded edges inside the second fold, the wider of the `top portions of the strip formed by the second fold forming the convex side of the reed and completely overlying the convex side pf the narrcwer portion ofthe strip formed by said second fold, the free edges f said portions meeting substantially at the edge of the reed with the edge of the wider portion extending slightly beyond and partially around the edge of said narrower portion to lock said vportions together.

2. A concave-convex paper imitation reed comprising a paper strip having its edges folded to a longitudinal line one side of the center line of. said strip and folded at said linie with the folded edges inside the second fold, the wider of the two portions of the strip formed by the second fold forming the convexV sideof the reed and completely overlying the convex side of the narrower portion o f the strip formed by said second fold.

3. The method of forming concavo-convex paper imitation reed comprising feeding ar strip of paper, folding the edges thereof to a longitudinal line at one side of the center line of the strip, moistening the folded in portions of the strip,

. folding the paper along said longitudinal line to enclose the folded in portions of the paper, and

then forming the folded strip into a concavoconvex form with the wider of the two portions of the strip formed by the second fold completely Voverlying the convex side of the narrower porr convex form with the wider of the two portions of the strip vformed by the second fold completely overlying the convex side of the narrower portion of the strip 'formed by said second fold with its free edge extending slightly Abeyond theyfree edge hesive is applied, we have been able `to produce of said narrower -portion and folding the free edge of said second edge partially around the free edge of said narrower portion.

5. The method of forming concave-convex pa per imitation reed comprising feeding a strip of paper, folding the edges thereof to a longitudinal line at the side of the center line of the strip, folding the paper along said longitudinal line to enclose the folded in portions of the paper and then forming the folded strip into a concavoconvex form with the wider ofthe two portions of the strip formed by the second fold completely roverlying the convex side of the narrower portion of the strip formed by said second fold.

6. The method of forming concavo-convex paper imitation reed comprising feeding a strip of paper, folding the edges thereof. to a longitudinal line at lone side of the center line of the strip, folding the paper along said longitudinal line to enclose the folded in portions of the paper and then bending the folded strip into a concavo convex form with the wider of the two portions of the strip formed by the second fold completely overlying the convex side of. the narrower portion of the strip formed by said second fold with its free edge extending slightly beyond the'free edge of said narrower portion and folding the free edge of said second edge partially around the free edge of said narrower portion.
